+--- 1.3.22 2012/02/02
+
+zoom: fix memory leaks.
+
+session_shared: maximum number of sessons is configurable. Default
+value is 100. Result-sets for backends without named result sets are
+only re-used if databases is identical for a search. This is under the
+assumption that performance may suffer for those backends when
+changing the database for each search.
+
+multi: combines diagnostics from all backends. All diagnostics from
+backends are combined into multiple non-surrogate diagnostics; rather
+than just one diagnostic from first backend.
+
+--- 1.3.21 2011/12/27
+
+zoom: relay realm to cproxy parameter file.
+
+Configuration: Allow filter collection element inside route. This
+makes it possible to include multiple filters at once.
+
+zoom: nocproxy also disables urlRecipe.
+
+--- 1.3.20 2011/12/21
+
+zoom: return diagnostic if CQL sortby conv fails.  Diagnostic Bib-1 214
+"Illegal sort relation" is returned. Gets translated to SRU diagnostic
+90: "Unsupported direction value".
+
+zoom: honor database argument nocproxy. This disables creating a content
+connector session (for non-CF targets, usually) and also relays nocproxy
+as database argument to a CF target.
+
+--- 1.3.19 2011/12/16
+
+zoom: Multiple proxy hosts may be given for proxy rich database 
+parameter. List is comma separated.
+
+http_file: decodes URI paths properly. Does not return 404: not found
+if no prefix are matches. Instead packages are passed on.
+
+--- 1.3.18 2011/12/08
+
+zoom: content-{user,password,proxy} are passed on to content proxy
+system and takes precedence over user,password,proxy .
+
+sru_z3950: SRU extra argument x-log-enable=1 enables a search response
+with a log element including log material from children filters. At
+this point, only the zoom filter uses this log facility. It will
+eventually be used by other filters as well. In particular it might be
+useful for this feature to track all filters in used during a search.
+
+zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
+and queries as they are manipulated are logged.
+
+zoom:  extend addinfo with native diagnostics. Diagnostics as received
+by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
+diagnostics. This indicates both a backend diagnostic and the original
+form.
+
+zoom: default urlRecipe value is ${md-electronic-url}
+
+zoom: target profile setting sruVersion is recognized.
+
+--- 1.3.17 2011/11/17
+
+zoom: log target profile record fetched (AKA Torus).
+
+--- 1.3.16 2011/11/17
+
+Change target profile parameter CfSubDb to CfSubDB.
+
+--- 1.3.15 2011/11/12
+
+zoom: bug fix: realm was relayed to CF targets by mistake (realm only
+makes sense to the zoom module itself).
+
+--- 1.3.14 2011/11/11
+
+zoom: realm may be given as part of database.
+
+--- 1.3.13 2011/10/26
+
+Fix Origin class assigment method; was removd by mistake in 1.3.12.
+
+--- 1.3.12 2011/10/26
+
+zoom: database args x-name=value are passed through to backend database.
+
+SRU filter: user may specify session ID that is passed to log entries
+that follows. It is specified by using x-session-id in the SRU arguments.
+
+zoom: fix null pointer reference which would occur for bad url parameter
+inside "torus" or if url was not given.
+
+--- 1.3.11 2011/09/09
+Fix bug in filter session_shared where sessions would not expire
+properly (session ttl). This in turn could make the target close the
+connection before expected and session_shared would return diagnostic
+2: system temporarily available.
+
+--- 1.3.10 2011/09/09
+
+zoom: new target profile setting: sortmap_field. If sortmap_field is given
+the field is mapped to the value for the sortmap. Values not matching
+sortmap_field are passed verbatim.
+  
+zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
+"cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
+depending on whether RPN or CQL is actually sent to the target.
+
+--- 1.3.9 2011/08/25
+
+zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
+
+zoom: For content proxy authentication is stored in param name
+"auth", instead of "authentication".
+
+--- 1.3.8 2011/08/22
+
+zoom: relay schema in SRU mode. Previously recordSchema was not affected
+by elementSet.
+
+--- 1.3.6 2011/08/22
+
+zoom: new target profile element literalTransform that holds XSLT
+(encoded as string) for target. Only if present and non-zero length it is
+considered present. This takes precedence over transform.
+
+Don't rely on trang anymore for Git checkout builds. Configuration in etc
+will only be properly validated if trang is available. From now on only
+relax NC files are bundled with the source dist.
+
+Updates to check for Boost unit test (autoconf stuff). On MacOSX this
+component was not detected when it should be.
+
+--- 1.3.5 2011/08/12
+
+z3950_client: mark non-surrogate diagnostics from backend.
+
+zoom: a proxy may be specified for HTTP fetch of target profiles.
+
+--- 1.3.4 2011/08/01
+
+Honor piggyback. Makes some SRU targets behave that insist on
+maximumRecords > 0, but also increases performance.
+
+--- 1.3.3 2011/08/01
+
+Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
+file was not update for libdir/metaproxy4 in version 1.3.2.
+
+--- 1.3.2 2011/08/01
+
+Change location of Metaproxy modules from libdir/metaproxy to
+libdir/metaproxy4. Directory libdir/metaproxy is also owned by 
+libmetaproxy3 and, thus, should not be used by libmetaproxy4.
+
+New facility to dump APDUs from zoom filter. Enabled by 
+<log apdu="true"/> in the zoom filter configuation.
+
+zoom filter bug fix: SRU diagnostics received from backend was
+not properly converted to Bib-1 diagnostics.
+
+Package metaproxy depends on libmetaproxy4, same version.
+
+--- 1.3.1 2011/07/28
+
+zoom: fix a bug WRT passing authentication parameters to backends.
+
+--- 1.3.0 2011/07/27
+
+Fixes for windows Makefile.
+
+--- 1.2.10 2011/07/25 
+
+Change major version of metaproxy library from 3 to 4. This in turn
+makes new package names for Debian and RPM.
+
+--- 1.2.9 2011/06/27
+
+zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
+transforn mode).
+
+zoom: configurable element sets for record transforms.
+    
+zoom: the target profile based transform is specified by element_transform
+in element torus of of the ZOOM filter configuration ; default value
+is "pz2". Target profile based retrieval is specified by element_raw
+in configuration. It will perform same steps, but omit the XSL transform.
+Default value is "raw".
+
+zoom: element set is omitted if not set in profile. But only if pz2
+transform is in effect. Previously the default element set was to "F".
+
+zoom: For non-CF targets database arguments are parsed. User may supply
+db,user=myuser&password=mypass for non-CF targets. These values override
+what's given the authentication from the target profile.
+
+session_shared: fix reference to freed memory. Would occur if a search
+response had non-surrogate diagnostics.
+
+--- 1.2.8 2011/06/22
+
+Route may be given for each port in frontend_net.
+
+--- 1.2.7 2011/06/22
+
+Documentation for zoom filter. Local target profiles may be specified.
+
+Fixes for zoom filter.
+
+--- 1.2.6 2011/06/15
+
+First version with zoom filter.
+
+--- 1.2.5 2011/05/06
+
+Filter z3950_client may be configured to always send a close APDU
+to backend target when connection/session is closed. This will only
+happen if close APDU is not already sent. Enabled by configuration
+for z3950_client (force_close).
+
+Filter virt_db and multi: relay close APDU.
+
+Filter virt_db and multi: relay init size parameters 
+preferredMessageSize and maximumRecordSize.
+
+Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
+
+--- 1.2.4 2011/01/27
+
+RPM package for Metaproxy works for both SLES11 and Centos 5.5.
+
+metaproxy-config: exec_prefix, libdir, includedir. Use these variables
+as determined by configure.
+
+RPM: Release includes 'indexdata' name. Use indexdata in release name so
+this package can be distinguished from other vendors.
+
+--- 1.2.3 2010/10/04
+
+Fix filter multi: relay idAuthentication parameters.
+
+--- 1.2.2 2010/09/15
+
+Add metaproxy-config for returning compiler flags, libraries.
+
+--- 1.2.1 2010/08/18
+
+Fix --with-boost=PREFIX .
+
+--- 1.2.0 2010/07/09
+
+session_shared: fix use of maintenance thread.
+
+Introduce 'start' method for filters and routers. It gets called after
+configure and after fork, but before processing. This changes API -
+from libmetaproxy2 to libmetaproxy3.
+
+--- 1.1.7 2010/06/30
+
+session_shared: ensure backend session is closed if init rejected
+is received.
+
+z3950_client: fix NULL ptr reference that could occur if two clients
+connected concurrently and if max-sockets was in effect.
+
+--- 1.1.6 2010/06/21
+
+Fix bug 3497 - Metaproxy unstable while stopping.
+
+Fix bug 3495 - SEGV in SRU filter.
+
+--- 1.1.5 2010/06/15
+
+Filter multi throws diagnostic 'Present Out of Range' when
+appropriate - rather than returning 0 records.
+
+Filter virt_db: fix bad result reuse. Could happen if a result
+was overriden and a backend did not supported named result sets.
+
+--- 1.1.4 2010/05/11
+
+Filter log: category access logs diagnostics even if searchStatus
+or presentStatus is 'success'.
+
+--- 1.1.3 2010/04/21
+
+The SRU to Z39.50 filter does repeated Z39.50 present requests
+to fetch all records. Needed when a Z39.50 server returns partial
+results (due to message size limits).
+
+--- 1.1.2 2010/03/18
+
+Metaproxy now kills all child processes that are spawned by
+modules (in case of fork, exec).
+
+--- 1.1.1 2010/01/28
+
+Debian package now installs /etc/metaproxy/metaproxy.xml which
+includes all XML files /etc/metaproxy/filters-enabled .
+The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
+
+--- 1.1.0 2010/01/20
+
+Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
+development package to facilitate 3rd party Metaproxy modules.
+
+--- 1.0.23 2010/01/04
+
+Filter virt_db: Close backend filter session when Init rejected is received
+from it (in which case it's not really closed yet). This will ensure we don't
+run out of resources such as FDs in this case.
+
+sru_z3950 filter: Accept any database (including those not listed).
+
+--- 1.0.22 2009/12/03
+
+Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
+later which means YAZ 3.0.47 or later.
+
+--- 1.0.20 2009/11/19
+
+For filter virt_db, the database is a glob pattern and the virtual
+database sections are consulted in the order given.
+
+--- 1.0.19 2009/07/08
+
+For filter multi, the target (for routing) may be given as a glob-pattern.
+
+More documentation for filters virt_db and multi.
+
+Update schema to allow for no database in sru_z3950 filter.
+
+--- 1.0.18 2009/06/30
+
+Added limit filter to put sleep (penalty) for heavy use.
+
+Filter frontend_net may be configured to limit the number of new connections
+from same IP to some value (connect-max).
+
+Fixed the load_balance filter.
+
+--- 1.0.17 2009/06/16
+
+Fix path for metaproxy executable for Debian init.d script.
+
+--- 1.0.16 2009/06/10
+
+SRU to Z39.50 filter honors x-username and x-password. If only
+x-username is given that translates to open authentication (Z39.50v2). If
+both x-username and x-password is present that translates to idPass
+authentication (Z39.50v3).
+
+New facility to change current working directory (-w).
+
+Update to upstream skeleton of init.d script. Should fix bug #2619.
+
+Filter session_shared now caches records (used to only cache connections
+and result sets).
+
+Filter session_shared now invalidates a Z39.50 session if a server
+returns -1 hits. This facility was also part of yazproxy and gets around
+a bug in Voyager-based Z39.50 servers.
+
+--- 1.0.15 2008/11/18
+
+Fixed reference counting bug in Z39.50 client module (could cause SEGV).
+
+--- 1.0.14 2008/06/09
+
+Fixed the value of SRU record schema in searchRetrieve response. It was set
+to a fixed value of "dc" before.
+
+Serialize identical SRU requests. This is useful if HTTP client software
+fires identical requests against metaproxy.
+
+Allow Z39.50 target to be specified for SRU requests by using SRU extra
+parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
+avoid static configuration. This facility is handled by the sru_z3950 module
+and the z3950_client module.
+
+Allow maximum number of sockets to be used for a Z39.50 client by the
+use of SRU extra parameter x-max-sockets. This facility is handled by the
+sru_z3950 module and the z3950_client module.
+
+--- 1.0.13.1 2008/02/29
+
+Simplified check for Boost libraries.
+
+--- 1.0.13 2008/02/29
+
+First Debian package.
+
+The sru_z9350 filter now recognizes SRU parameter z-target as being
+a ZURL of the form host/database . 
+
+Mergetype may be specified for filter 'multi'.
+
+--- 1.0.12 2007/09/19
+
+Fixed problem in Makefile WRT library specifictions. This could produce
+linker errors (when they should not happen).
+
+Fixed bug #1341: MetaProxy returning different results. Problem was that
+fix-up of record database did not normalize the database name.
+
+Documentation updates for Windows compilation.
+
+--- 1.0.11 2007/06/14
+
+Fixed problem with logfile being truncated.
+
+--- 1.0.10 2007/05/23
+
+Fixed bug #1136: Access rights not enforced.
+
+Extension for log module. The log category 'access' logs more details.
+New category 'user-access' added which is simlar to 'access' but adds
+the Z39.50 user as for all entries in a session.
+
+Switched to GPL v2.
+
 Added support for configurable default/force target/vhost for module Z39.50
 client module.
